Effective immediately, any horse testing positive for clenbuterol in out-of –competition testing at Los Alamitos will be placed on the Veterinarian’s List (Veterinary Treatment-Medication) for a minimum of 15 days and will be required to test clear of clenbuterol in both blood and urine before being removed from the Veterinarian’s List and being allowed to start. The blood and urine sampling must be done in the test barn under the supervision of CHRB official veterinarian Dr. Beck.

All horses within CHRB inclosures are subject to out-of -competition testing. However, horses qualifying for the Two Million Dollar Futurity and the Champion of Champion can expect special scrutiny leading up to those races.
